Description Milan Kubec 2004-05-18 11:23:14 UTC 
[dev-200405171800, JDK 1.5.0]
First open of ant script is very slow, takes about
3-4 sec., any next opening of any other script is
fast.
Comment 1 Jesse Glick 2004-05-18 14:37:28 UTC 
Probably it is loading and introspecting the Ant installation for
purposes of code completion. I don't know if there is anything that
can be done differently other than deferring the pause until some
later time, or pushing some of the delay forward into the init warmup
sequence, etc.
Comment 2 Jesse Glick 2004-06-07 14:56:37 UTC 
I believe this is fixed, since the new tree GUI should not need to
load IntrospectedInfo. You will still pay the first time you invoke
Ant code completion or run a script.
Comment 3 Milan Kubec 2004-06-23 10:17:49 UTC 
Yes, expanding Ant script node is much faster now. Verified in
dev-200406230100.
